Another year, another 🪐

#Saturn #Astrodon #Astrophotography

📷 2015, 2016, and then annually from 2020.

7 telescopic views of Saturn arranged in a horizontal line. All Saturns are tilted approximately 45° (the planet's north pole 'pointing' off to the top left). Left most images fuzzier, and with the rings more open, as the images progress to the right they get sharper, and the rings become more and more 'edge on'.

Amazing. So how do you do it now? What's your gear and method?

@tio Thanks! I have an 8 inch reflector imaging at 3000mm. Processed with Siril and Darktable

So do you basically record videos with a special telescope camera then process the frames?

I am trying too, in my amateur way tiotrom.com/photos/ and I'd like to up my game :) but I do not have any advanced gear. Actually I take all of my photos with an old Pixel 4a.

@tio I like your work! Yes, videos with an Astro cam these days. My early images on the left were a phone through the eyepiece of a telescope

Thanks! Maybe one day I'll get an astro cam because I see the difference in image quality is really huge, as it is to be expected. Excited to try that in the future!

it's just unfair how much better looking saturn is than the rest

This is awesome, keep it up! I like how the angle changes along with the resolution.

do they become sharper because your instruments are better or because it's getting closer?

@jesusmargar my instruments and processing improved, but Saturn is also getting to a higher altitude in my sky each year. The last 3 years were taken with the same setup

am I wrong or is 2023 the best of the series so far? Is it getting lower now?

@jesusmargar well observed, I haven’t had good atmospheric conditions this season yet, if I get a night of good seeing I will be able to exceed 2023. Saturn at opposition will climb in altitude for me until 2034

@jesusmargar even though it's not as sharp as the 2023 photo, it seems the 2024 photo captured a few moons?

@llewelly @jesusmargar well noticed, this is the first year I included the moons. I wasn’t happy with my blending until now

@llewelly Yes, I did notice that but I think moons may happen to be in the wrong place when pictures are taken (so that they don't reflect light, e.g. if they are 'behind') or any postprocessing may erase them, taking them for noise. Saturn has over a 100 moons (I am not sure we know all of them for certain) but only the biggest would be noticeable.

@jesusmargar @llewelly the moons require a bit of extra processing to bring out. They’re not lost to noise, the stacking process increases the signal to noise ratio

Is it getting less blurry because our cameras are better, or some other reason?

@ruawhitepaw I got better gear, and learned better capturing and processing skills. It’s been getting higher in the sky too which has helped

Oh it's *your* photos! Nice! I thought they were just the run-of-the-mill professional astronomy pictures.
